The invention also relates to a building, such as in particular a residential, office and / or commercial building, with a building hot water preparation system comprising a primary heating circuit for generally providing thermal energy to the building, and with at least one domestic service water system for providing service water to an apartment in the building and / or with at least one comprising a secondary heating circuit

tion for generating hot water.

The invention also relates to a method for operating a home station of an apartment in a building, in which domestic hot water for a home installation of the apartment is generated within an installation room of the home station by means of primary heating water of a primary heating circuit of a general building installation of the building, and in which

The invention also relates to a use of a heat exchanger and / or a mounting space for a heat transfer

carrier at a home station.

In particular, generic home stations are known from the prior art. Such apartment stations are used to provide primary heating water generated by a building installation of a central heating system in an apartment for domestic hot water preparation within the apartment and / or for the apartment heating of this apartment. Here, the thermal energy of the primary heating water heated by the central heating is transferred to the domestic water for the apartment or to a secondary heating water of the apartment heating, so that using the primary heating water, on the one hand, domestic hot water in the apartment and, on the other hand, preferably also domestic heating water can be generated. In order to be able to transfer the thermal energy inherent in the primary heating water to the domestic water and / or to the primary heating water, the home station is required

equipped with suitable heat exchangers.

The problem with known apartment stations is that the domestic water in the apartment station is often warmed up by the thermal energy carried into the apartment station by the primary heating water, even though no domestic hot water is requested at an apartment tap. Through this thermal energy, the "sta-

energy, which should ideally be minimized.

The invention is based on the object of further developing generic home stations, in particular in order to

to overcome the disadvantages mentioned.

The object of the invention is achieved according to a first aspect of the invention by a home station for transferring thermal energy from a general building installation to a home installation with an installation room in which both sanitary installation facilities and heating installation facilities are arranged, the sanitary installation facilities and the heating installation facilities within the installation room by means of a separation area

are separated from each other.

Due to the spatial separation of sanitary installation devices and heating installation devices within the home station, in particular within the installation room, it is structurally very simple to subdivide the home station into a cold side and a warm side, with the sanitary installation devices essentially on the cold side and the heating installation devices accordingly in

Are essentially located on the warm side.

The term "warm side", on the other hand, denotes that area of the home station that is always thermally heated by heating installation equipment, such as a primary heating circuit and, if applicable, a secondary heating circuit, if available.

is burdensome than the cold side.

Here, at least the primary heating circuit is designed as a high-temperature circuit with hot water temperatures above 55 ° C. or preferably above 60 ° C. or more. The secondary heating circuit can be operated at similar temperatures in order to supply the apartment's radiators with sufficient heat. The temperatures of the secondary heating circuit are often well below the hot water temperatures of the primary heating circuit, for example around 30 ° C for supplying a floor heating system.

heating of the apartment with appropriate heat.

In this respect, the warm side is more common within the meaning of the invention

or warmer than the cold side for longer.

In any case, by means of the present invention, the temperature of the domestic water inside the apartment station at the sanitary installation devices can be below 40

° C, even if no

and the domestic water is in the home station.

Thus, the spatial separation at the present apartment station significantly reduces the risk that thermal energy, in particular a primary heating water, from a primary heating circuit of the heating installation equipment of the general building installation is inadvertently transferred to the sanitary installation equipment of the apartment. This means that there are fewer unintentional energetic losses at the home station, which means that the home station at hand is operated more energy-efficiently.

can.

In addition, the risk is particularly advantageous that on the part of the sanitary installation equipment of the apartment installation inside the apartment, in particular in the apartment station, temporarily "standing" service water is unintentionally and critically heated by the thermal energy of the primary heating water or possibly also by the secondary heating water. This also minimizes the risk of domestic water becoming contaminated, in particular the risk of critical legionella formation within the home station.

least significantly reduced.

In other words, by means of the proposed spatial separation, the home station, in particular the installation room, is at least in a cooler sanitary installation area, in which there are essentially sanitary installation facilities, and in a thermal

ren heating installation area, in which essentially

divided.

In particular, a thermal separation with regard to different functional areas within the apartment station is achieved in the present case in a structurally simple manner, namely a separation of a hot area, which is preferably always heated by the primary heating water of the general building installation, and a cold area, which is only heated as required by specifically the primary heating water or, if necessary, by secondary heating water when domestic hot water is supplied to an apartment

tap is requested.

Such a separation area can, for example, be achieved without any components and with greater distances between the sanitary installation devices and the heating installation devices. A thermally more effective separation area can cumulatively or alternatively also be achieved within the apartment station by means of suitable physical separation means, for example by means of appropriate insulation means, which are installed on sanitary installation devices or on heating installation devices

be attached, or the like.

In the context of the invention, the term “home station” describes a thermal energy transfer station which is preferably arranged within the home. This means that such a home station is assigned to each apartment in a building, whereby with the help of the home station, apartment-specific thermal energy from a primary heating circuit of a general

building installation and assigned to one of the apartment

can be warmed.

At this point, the term “apartment” should also be explained in more detail, as it is to be understood in the context of the present invention. In the present case, an apartment represents an independent building unit of a building which is individually delimited from other parts or building units of the building, in particular is spatially separated from them, and which in this respect also preferably represents an independent functional unit within the building. In this respect, the apartment is also considered to be an independent, self-contained building unit compared to other areas of the building. In this context, an apartment within the meaning of the invention can be a privately used building unit, a publicly used building unit, a commercially used building unit, or the like. Here, an apartment within the meaning of the invention is not only used for residential purposes, but also cumulatively or alternatively for actual purposes, commercial purposes, in order to clarify only the essential purpose of an apartment here.

For the sake of simplicity, in the context of the present description, claims, figures, etc., only one apartment is spoken of throughout, in the sense of the invention

corresponding variants are always implied.

building involved.

In this context, the term “building” denotes a structure that is at least temporarily permanently connected to a building site or subsoil, i.e. in particular a property. The building has at least one room that serves as a dwelling for the purposes of the invention. In the context of the invention, a building can in the present case also be designed as a multi-building complex

be.

The term “building technology system” describes a basic supply installation for a building, in particular with regard to a stomach water and / or heating water heating system, this building technology system having a general building installation with at least one primary heating circuit and at least one apartment installation assigned to an apartment, and with thermal energy from the primary heating circuit of the building installation into which at least one apartment installation can be fed, namely by means of one assigned to the apartment, preferably one arranged within the apartment,

Home station.

In this respect, it is provided that the building technology system building installation-side connection devices of a primary heating circuit on the one hand and apartment installation-side connection devices of a service water system and / or residential

connection devices on the installation side of one second

has, which are arranged within the home station.

In the context of the invention, the term “installation space” describes an installation space of the home station that is enclosed by an envelope, in or through which sanitary installation devices and heating installation devices are at least partially led into or through, that is to say arranged. In this respect, the home station has an envelope that surrounds this installation space.

Such an envelope can be designed at least partially differently within an apartment, for example also by masonry, with the enclosed installation space being closed from the outside through a closable wall opening.

is accessible.

However, the envelope is preferably formed by an independent housing of the home station, so that the home station is mobile before installation, and preferably factory

can also be pre-installed with installations on the side.

A housing preferably surrounds the installation space of the home station, this housing preferably having a rear wall, a surrounding frame formed by side walls, and a front wall, the front wall realizing a lockable access to the installation space, for example in the form of a pivoting door and

a removable cover part.

In other words, the installation space is divided into a sanitary side and a heating side, the heating side (warm side) and the sanitary side (cold side) being spatially and thermally separated from one another, namely by a separation area (neutral zone).

stood.

Furthermore, the expression “sanitary installation devices” defines installation devices belonging to the apartment installation, which are at least partially or wholly arranged within the apartment station. In particular, these sanitary installation facilities also include installation facilities for a warm

domestic hot water preparation within the apartment.

The expression “heating installation equipment”, on the other hand, describes installation equipment for primary heating (general building installation) and possibly secondary heating (apartment installation), which at least

are partially arranged within the home station.

The home station is set up in such a way that, on the one hand, thermal energy from the primary heating circuit of the general building installation is used, especially in this home.

In the present case, heating installation devices are at least partially thermally connected to sanitary installation devices within the apartment station in such a way that thermal energy from primary heating water and / or secondary heating water from heating installation devices can be transferred to the domestic water of the apartment installation in a controlled manner in order to generate domestic hot water as required within the apartment station.

Such a heat energy transfer preferably takes place by means of a suitable heat exchanger which is arranged within the home station, more precisely in the installation room of the home station. As a rule, this is a water-to-water heat exchanger, which is preferred

In this regard, suitable heat exchangers are known from the prior art, so that their structure, mode of operation, connections or the like are not described further here

day area are spatially separated from each other.

The fact that there is a spatial separation of sanitary installation devices and heating installation devices within the home station, in particular within the installation space, by at least one heat exchanger assembly area, makes the home station particularly compact. The home station can thus be structurally advantageously divided into a cold side and a warm side, with the sanitary installation equipment essentially on the cold side and the heating installation equipment essentially on the cold side.

are located accordingly on the warm side.

By means of the deliberate spatial arrangement of the heat exchanger assembly area, namely between the sanitary and heating installation areas created in this way, the risk is significantly reduced at this apartment station that thermal energy, in particular a primary heating water, from a primary heating circuit of the heating installation installation

on facilities of the general building installation inadvertently

can be operated more efficiently.

Particularly advantageous is also reduced the risk that the sanitary installation equipment of the apartment installation inside the apartment, in particular temporarily "standing" service water in the apartment station, is unintentionally and critically heated by the thermal energy of the primary heating water or, if necessary, also of the secondary heating water. This also minimizes the risk of domestic water becoming contaminated, in particular the risk of critical legionella formation within the home station.

least significantly reduced.

In other words, by means of the proposed arrangement of the heat exchanger assembly area within the installation area, the home station, in particular the installation room, is deliberately placed in a sanitary installation area, in which there are essentially sanitary installation facilities, and in a heating installation area, in which there are essentially heating technology In -

installation facilities are divided.

In this way, a thermal separation with regard to different functional areas within the home station is achieved in a structurally simple manner, namely a separation of a hot area, which is caused by the primary heating water of the general building

installation is preferably always heated, and a cold

an apartment tap is requested.

Advantageously, through the heat exchanger assembly area proposed here, the heat exchanger installed there can also be used as a spatial separating means in the sense of the

An even more effective spatial separation between sanitary installation devices and heating installation devices within the home station can be achieved if the partition area or the heat exchanger assembly area has at least one partition, preferably two partition walls arranged at a distance from one another. If the partition area has such a partition wall, an improved thermal separation between a sanitary installation area and a heating system can be achieved within the home station.

installation area can be realized.

For example, a heat exchanger can be arranged in the sanitary installation area of the apartment station, and the cooler sanitary installation area and the heat exchanger are spatially and thermally separated from the warmer heating installation area by means of a partition. In this case, the sanitary installation area can comprise the partition area or the heat exchanger installation area, while the partition area or the heat exchanger installation area is separated from the warmer heating installation area by the partition

In other examples, the heat exchanger can be used both in relation to the sanitary installation area and in relation to the heating installation area by means of a partition wall in each case

It is particularly advantageous if the separation area or the heat exchanger assembly area is ventilated here, as shown

explained in more detail elsewhere.

According to a third aspect of the invention, the object is also achieved by a home station for transferring thermal energy from a general building installation to a home installation with an installation room in which both sanitary installation facilities and heating installation facilities are arranged, and with a heat exchanger on which both sanitary installation facilities and heating installation devices are connected, solved, with fluidic connections of sanitary installation devices and fluidic connections of heating installation devices on different sides of the heat exchanger, in particular on opposite sides, within the installation space.

lying sides of the heat exchanger, are arranged.

technical installation equipment.

In particular, with such a structural design, in particular with the heat exchanger appropriately placed within the installation space, a separation area within the home station within the meaning of the invention between sanitary installation equipment and hot

technical installation facilities are created.

In any case, this also reduces the risk that thermal energy, in particular a primary heating water, from a primary heating circuit of the heating installation devices of the general building installation is inadvertently transferred to the sanitary installation devices of the apartment. This means that there are fewer unintentional energetic losses at the home station, which means that the home station at hand is operated more energy-efficiently.

Particularly advantageously, the different connection sides also reduce the risk that on the part of the sanitary installation devices of the apartment installation within the apartment, in particular in the apartment station, temporarily "stagnant" hot water is caused by the

Thermal energy of the primary heating water or possibly also

at least significantly reduced within the home station.

In other words, the home station, in particular the installation room, is at least easy in a sanitary installation area in which there are essentially sanitary installation facilities, and in a heating installation area in which there are essentially heating installation facilities.

can be subdivided.

In particular, by means of the different connection sides, an improved thermal separation with regard to different functional areas within the apartment station is achieved in a structurally simple manner, namely a separation of a hot area, which is preferably always heated by the primary heating water of the general building installation, and a cold area, which is only heated as required by the primary heating water in particular when domestic hot water

is requested at an apartment tap.

Fluidic connections can be designed in many ways in the sense of connection devices, for example as connection

connection piece, connection bottle or the like.

In addition, it is advantageous if the home station,

in particular the installation space, partially, preferably a

Separation area or a heat exchanger assembly area, independent

facilities can be cooled passively or actively.

If the home station can be at least partially cooled, the sanitary installation area in particular can be kept cooler than the surrounding areas within the home station. In this respect, the installation space can be subdivided accordingly into air-conditioned and non-air-conditioned functional areas.

The description "independent of sanitary and / or heating installation facilities" makes it clear that it does not mean that the home station or the installation room, and in particular the sanitary installation facilities of the home station, such as a heat exchanger, are cooled by freshly supplied service water

the. Rather, air cooling should be understood here.

In other words, the home station can be at least partially passively or actively cooled, regardless of the

domestic hot water or fresh water or heating water.

In this case, the separation area or the heat exchanger assembly area is preferably air-conditioned or air-conditioned in the sense of the invention.

Passive cooling within the home station can be structurally simple, for example, through a suitable air duct, in particular through an air duct or ventilation duct designed in terms of flow technology, through air ducts.

baffles and / or through ventilation slots, or the like

ling.

The terms ventilation duct and air duct are

used synonymously within the meaning of the invention.

According to the invention, active cooling can be achieved within the home station, for example, by an activatable fan device, by means of which a switchable air flow within the home station is established.

can be lated.

In any case, it is advantageous in the present case if the separating area or the heat exchanger assembly area, in particular the heat exchanger, is flushed with cooler ambient air

or can be washed around.

According to a fourth aspect, the object of the invention is also achieved in this respect by a home station for transferring thermal energy from a general building installation to a home installation with an installation room in which both sanitary installation devices and heating installation devices are arranged, the home station being one that can be activated Has temperature control device, which is different from heat input and / or heat dissipation, plumbing and / or heating installation devices, and

by means of which the installation space is independent of sanitary

at least partially can be actively tempered.

By means of the activatable temperature control device proposed here, the installation space can be cooled if necessary or cooling can be actively intensified. In particular, the home station can be subdivided into a cold side and a warm side in a particularly operationally reliable manner, namely into a cold side with sanitary installation devices and into one

Warm side with heating installation equipment.

By means of the activatable temperature control device, a separating area within the meaning of the invention between sanitary installation devices and heating installation devices can advantageously also be created within the home station

be created.

In any case, this solution also reduces the risk that thermal energy from a primary heating circuit or a secondary heating circuit of the heating installation devices unintentionally heats the sanitary installation devices arranged within the apartment station. This means that there are fewer unintentional energetic heat losses at the home station, which means that the available home station

on can be operated more energy-efficiently.

Particularly advantageous is also reduced the risk that on the part of the sanitary installation equipment of the apartment installation within the apartment station temporarily "stagnant" service water is caused by the thermal energy of the primary

heating water or, if necessary, secondary heating water

station significantly reduced.

Furthermore, it is advantageous if the activatable temperature control device has a cooling area within the installation space, which is arranged differently from a sanitary installation area of the installation space and / or a heating installation area of the installation space, preferably spatially separated, particularly preferably thermally separated. For example, this cooling area includes the present separation area or heat exchanger assembly area. The cooling area can also be particularly effectively removed from the surrounding area by partition walls running within the installation area.

In this respect, it is advantageous if the temperature control that can be activated

device is characterized by a cooling device.

Simple cooling can already be achieved if the activatable temperature control device comprises a fan device or fan device. One is also conceivable

Air conditioning device. The activatable temperature control device can work particularly effectively if it is located within the cooling area in the apartment

station is arranged.

For example, the fan device and / or

the air conditioning equipment within the home station

be strengthened.

It is useful if the temperature control device that can be activated is temperature-controllable, in particular as a function of a temperature sensor which is arranged in particular within a separation area or a heat exchanger assembly area. In this way, for example, a fan device can only be switched on if a mere chimney effect alone is not sufficient for cooling. In this respect, an appropriately equipped home station can energetically

be operated more sensibly.

According to a fifth aspect of the invention, the object is also provided by a housing for a home station for transferring thermal energy from a general building installation to a home installation with a rear wall, with a front wall and with side walls, by means of which an installation space of the housing for arranging sanitary installation devices , is housed by heating installation devices and by at least one heat exchanger, the installation space of the housing being divided into a sanitary installation area and a heating installation area by means of at least one partition

is spatially divided.

on facilities.

With the present housing, the home station is significantly less likely to inadvertently transfer thermal energy from a primary heating circuit of the heating installation equipment of the general building installation to the sanitary installation equipment of the apartment. This means that there are fewer unintentional energy losses on the housing of the home station, which means that the home station constructed with such a housing is energy-efficient.

ter can be operated.

In addition, it is particularly advantageous that the risk of temporarily “standing” service water being unintentionally and critically heated by thermal energy from primary heating water or possibly also from secondary heating water on the part of the sanitary installation devices within the housing is particularly advantageous. As a result, there is also the risk of contamination from service water, in particular the risk of critical legionella formation, within the housing of the home station

reduced.

se a mobile envelope for the present home station.

If a separation area and / or a heat exchanger assembly area is arranged between a sanitary installation area and a heating installation area, a thermal separation from a sanitary installation area and a heating installation area can also be effectively implemented. As already described at the beginning, such a separation area and / or heat exchanger assembly area can be designed differently on the present heat exchanger, in particular

re with a partition or preferably several partition walls.

The home station and in particular the installation space of such a home station can be divided spatially differently, for example symmetrically with regard to the sanitary installation and heating installation area. This means that the sanitary installation area and the heating installation area have essentially the same basic

have area.

niche installation facilities are provided.

If the separation area and / or the heat exchanger assembly area is arranged off-center within the installation space, with the sanitary installation area being smaller than the heating installation area, there is more installation space available on the heating installation side due to the larger floor area available for the installation of heating installation devices. This is advantageous, for example, if the home station in the heating installation area has components of both a primary heating

circuit as well as a secondary heating circuit, etc.

As a rule, less installation space is required in the sanitary installation area, since there essentially "only" components

the domestic hot water preparation are housed.

It goes without saying that reverse installation space conditions can also be set up at the home station, so that, for example, the sanitary installation area can be designed to be larger. This can be advantageous, for example, if a post-heating device, in particular an electrical post-heating device, such as an electrical instantaneous water heater or the like, is to be optionally arranged or retrofitted on the part of the sanitary installation area

To heat domestic hot water before or at the end.

can be provided.

In the present case, the base area preferably relates to the

Rear wall of the home station.

In addition, it is advantageous if a separation area, in particular a heat exchanger assembly area for arranging a heat exchanger and / or a heat exchanger, is thermally insulated from the installation space, in particular from a sanitary and / or heating installation area

of the installation room.

Thermal insulation of a cold side with sanitary installation devices of the apartment station from a warm side with heating installation devices of the apartment station is particularly effective if a separating area within the installation space is thermally insulated, so that preferably a sanitary installation area and a heating installation area within the apartment

station can be arranged spaced from each other.

For improved thermal insulation, suitable in

partitions arranged in the installation space, in particular

the installation room can be controlled in a targeted manner.

Cumulatively or alternatively, other insulating components can also be arranged within the dwelling station, for example one or more shell parts, which are preferably made from thermally insulating materials, such as

such as highly porous plastic materials.

In general, thermally insulating materials can be used at the apartment station, for example synthetic insulation materials such as expanded polystyrene rigid foam (EPS), extruded polystyrene rigid foam (XPS), polyurethane (PU) or the like, mineral insulation materials such as glass or rock wool , Foam glass or the like, near-natural insulation materials such as wood fibers, cellulose, etc.,

just to name a few examples.

Furthermore, it is advantageous if at least one partition wall between the sanitary installation devices and the heating installation devices, in particular in some areas, has a double web wall area with a cavity. By means of a double web wall or such a double web wall area, thermally insulating effects can be reinforced again. If a corresponding cavity is cumulatively provided here, in addition to the thermal effect of a thermally insulating partition wall material, a further insulator can be installed on the at least one partition wall within the apartment station and between the sanitary installation area

and the heating installation area, namely

chen.

If the cavity is opened with a cavity opening to at least one outside of the housing, air that has been warmed up in the cavity can, if necessary, exchange very easily with ambient air, whereby a suitable

real cooling.

In terms of construction, such passive cooling can be implemented or improved at the home station if the cavity opening and a ventilation opening of the home station are arranged congruently. This applies in particular to a corresponding ventilation opening on the housing of the residential

terminal to.

Furthermore, it is also advantageous in this context if the rear wall and / or the front wall of the home station has at least one ventilation opening which is arranged congruently with an opening in a cavity of a double web wall area of at least one partition, as this allows ambient air from outside the home station to enter a partition area , a heat exchanger assembly area, or a ventilation duct or air duct of the home station. This can reduce the cooling effect even further.

area and / or a heat exchanger assembly area.

are directed, an air curtain between a plumbing

and the heating installation area can be created.

The term "air curtain" describes in the context of the invention a thermally insulating device of the home station, in particular within the installation room, by means of which a transfer of thermal energy from the warm side of the home station to the cold side of the home station can be prevented or at least significantly reduced, the air curtain in particular consists of an air volume flow, which at least partially passes through the home station

is directed.

It goes without saying that such an air curtain can be implemented structurally differently on the present home station. For example, an air curtain can be generated passively, for example by a chimney effect due to rising warm air, or an air curtain can, if necessary, also be actively generated or actively reinforced, for example by an electrically operating and

switchable fan device. The air curtain can be favored by means of two suitable

Spaced apart partition walls inside

be separated.

In this context, it is advantageous if the separation area and / or the heat exchanger assembly area is open to the outside of the home station, in particular a housing of the home station, so that there is enough supply air or fresh air from outside the home station to generate an air curtain can be sucked in by means of the home station. In this respect, the home station is set up to suck in ambient air from outside the home station and to pass it through the home station as a volume flow in areas and then out again

to the home station.

If a ventilation channel is provided within the installation space, which has at least one ventilation opening in the home station, in particular in a housing of the home station, areas to be cooled within the home station can be more targeted, for example with ambient air

be charged in order to achieve appropriate cooling effects.

It is therefore useful if the home station and / or the housing has such a ventilation duct. In this way, an air curtain can also be used for thermal insulation

tion can be guided through the home station in a more targeted manner.

The ventilation channel is preferably closed on its narrow sides

the outside of the home station, especially a housing

voltage station can be realized.

For example, ambient air can flow into the home station or into the ventilation duct on the underside of the home station and flow through the home station, in particular through the separation area or the heat exchanger assembly area, and then exit the home station again at the top of the home station. In this case, a heat exchanger is preferred which is arranged inside the apartment station and the volume flow flows around or around it on the outside. In this way, in particular the separating area or the heat exchanger mounting area and preferably

the heat exchanger can also be cooled.

Cumulatively or alternatively, it is advantageous if the ventilation duct is partially open on its long sides to the outside of the home station, in particular a housing of the home station, so that exclusively or additionally ambient air flows into the installation room.

In this respect, it is advantageous if the home station and / or the housing has a large number of ventilation openings in order to ventilate the installation space, the ventilation openings having openings from outside the home station, in particular into the separation area or the heat exchanger assembly area,

and especially in the ventilation channel.

It does not matter whether the side walls are through a housing of the home station and / or through a masonry

the apartment surrounding the home station are formed.

It is also advantageous if at least one partition wall or preferably several partition walls of a partition area or a heat exchanger assembly area are arranged to run between two opposing housing walls of the home station. In this way, an air curtain and, in particular, a ventilation duct from bottom to top between two housing walls of the home station can also be advantageously formed.

are formed.

In order to be able to establish a fluidic connection between the separation area and the sanitary installation area on the one hand and the heating installation area on the other hand, within the apartment station, it is advantageous if at least one partition wall between the sanitary installation equipment and the heating installation equipment has a connection opening or preferably two connection openings for the implementation of installation equipment.

In addition, the thermal insulation on the at least one partition wall can be further improved if connection openings for installation devices within the home station are made by means of sealing means that adapt flexibly to the contours of installation devices and / or partition wall edges, such as glass or rock wool, or later.

hardening foam materials, are sealed.

It is particularly advantageous if a mounting device for an activatable temperature control device, in particular for a fan device, is arranged within the installation space, in particular within a separation area, a heat exchanger mounting area and / or a ventilation duct, the home station or the housing. By means of such a mounting device, an activatable temperature control device or a fan device can be arranged precisely in a stationary manner in the installation space, so that, for example, an air volume flow within the installation space is operationally stable.

A particularly preferred embodiment variant provides that an interior cold temperature T 1; prevails, which is 5%, preferably 10% or 15%, or ideally 20% lower than an indoor warm temperature T, in a heating installation

area of the installation room.

Even with a cold interior temperature Tx that is 5% lower than the warm interior temperature T, of the heating installation area, the home station can be operated more effectively in terms of energy.

If the cold interior temperature Tx is around 10% or 15% below the warm interior temperature Tw, there may be a risk of contamination from the domestic hot water inside the home station.

In buildings with a large number of apartments in particular, building technology systems are increasingly being equipped with a building installation which generally provides thermal energy to the individual apartments of the building by means of a central building hot water preparation system comprising a primary heating circuit. This thermal energy generally provided by means of the hot water or primary heating water can be tapped with the help of the apartment station assigned to each apartment and individually sent to the domestic hot water system or to the apartment heating system, in particular to its secondary

A spatial or thermal subdivision can be achieved in different ways, as in the present case at other points

is described in detail.

Furthermore, according to a ninth aspect of the invention, the object is also provided by a method for operating a home station of an apartment in a building, in which domestic hot water for a home installation of the apartment is generated within an installation room of the home station by means of primary heating water of a primary heating circuit of a general building installation of the building, and in which by means of a heat exchanger arranged within this installation space, thermal energy is transferred from the primary heating water to domestic water in order to provide the domestic hot water for the apartment, the apartment station being flowed through at least in some areas by means of an air volume flow in order to transform the installation space into a sanitary installation area with sanitary installation facilities and

The new division of the installation space into a sanitary installation area and a heating installation area in particular enables the installation space of the home station to be thermally divided, namely into a cold side of the home station and a warm side of the home station. As a result, the risk of an unintentional critical heat energy transfer from the warm side to the cold side can be significantly reduced, so that, on the one hand, an advantageous energetic operation and, on the other hand, a reduction in the risk of contamination from standing service water.

Such an undesirable critical transfer of thermal energy from the warm side (heating installation area with heating installation facilities) to the cold side (sanitary installation area with sanitary installation facilities) occurs within the meaning of the invention, for example, when the domestic water temperature from the “standing” ascites water within the apartment station never exceeds a value above 45 ° C, in particular above 50 ° C or 55 ° C, is reached or exceeded solely due to the interior temperature prevailing in the apartment station, i.e. bypassing the operation of the heat exchanger arranged in the apartment station, which is intended for regular domestic water heating.

It is particularly advantageous if such supply air openings and / or exhaust air openings are arranged in side walls of a housing of the home station. Exhaust air openings are preferred

The home station 1 has an installation room 7 in which on the one hand sanitary installation devices 10 and on the other hand heating installation devices

directions 11 are located.

The installation space 7 is delimited by a housing 15 of the home station 1. To this extent, the housing 15 in this embodiment is an envelope (not shown separately and numbered) of the home station 1, by means of which the installation space 7 of the home station 1 from the

Environment 16 is demarcated.

The housing 15 here has a rear wall 18, a removable front wall 19 (see Figure 3), a lower side wall 20, an upper side wall 21 and a left side wall 22 and a right side wall 23, the side walls 20, 21, 22 and 23 as a whole a circumferential frame 24 of the housing 15 or

of the home station 1.

The installation space 7 is in a plumbing installation

must be assigned to home station 1.

A separation area 30 is advantageously arranged between the sanitary installation area 26 and the heating installation area 27, by means of which the sanitary installation devices 10 from the heating installation devices 11 both spatially and thermally

are separated from each other.

As a result of this separation achieved by means of the separating area 30, it is always possible to maintain a significantly lower interior temperature T% x in the sanitary installation area 26 than in the heating installation area 27, in which a higher interior temperature Tw "prevails due to the heat input from the heating installation devices 11. In other words, the separation area 30 ensures that the interior temperature of the sanitary installation area 26 is always below the interior temperature of the heating installation.

In this respect, the apartment station 1 and thus also the installation room 7 is in a cold side 31, on which the sanitary installation area 26 with its sanitary installation devices 10 is located, and in a warm side 32 on which the heating installation area 27 with its heating installation devices 11 is arranged,

This alone enables a spatial and / or thermal separation of the sanitary installation area 26 and the heating installation area 27 within the installation space 7, even without the other features of the invention if the heat exchanger 1 is alternatively physically connected to the lower and upper side walls 20 and 21 by means of suitable connection parts (not shown here). Furthermore, it is also conceivable that the heat exchanger 1 is designed in such a way that the heat exchanger 1 itself physically extends from the lower side wall 20 to the upper side wall 21, in order hereby only briefly a few

By means of the ventilation duct 60, an air volume flow 65 is directed through the separating region 30 in a targeted manner; here also through the heat exchanger mounting area 50, so that the
